Abstract: AMMI model was used to analyze the result of Hefeng47 that attended soybean regional trials in the second accumulated temperature belt of Heilongjiang province and southwest temperature Sanjiang Plain sub-humid zone(five zones).The result indicated that the yield of Hefeng47 was the first among all the varieties used in trail,while Di value of Hefeng47 was the second and lower than the check.Hefeng 35 Therefore the adaptability of Hefeng47 was superior to Hefeng35.According to the interaction of variety and experiment places,Hefeng47 was suitable to promote to grow in the second accumulated temperature belt of Heilongjiang province and southwest temperature Sanjiang Plain sub-humid zone(five zones),including Tangyuan,Huanan,Fujin,Youyi,Bijia mountain,Yilan and et al.Stepwise regression method was adopted to obtain the yield regression equation for Hefeng47 which was:Y=4056.6248-39.1945X₁+14.4335X₄ +38.9511X₆+37.42421X₇.It showed that effective branchy stem contributed most to the yield of Hefeng47,following by the number of plants per square,lastly the weight of one hundred seeds.

Key words: Hefeng47, Yield evaluation, Stepwise regression
